Lung transplantation is now considered one of the effective management of end stage pulmonary diseases. This review presents the recent progress of primary graft failure in lung preservation, such as low temperature, ventilation, etc. The purpose is to provide some valid methods in clinical practice.

From April.1993 to Jan.1994,transcatheter maxillary arterial chemoem- bolization using Cisplatin microspheres(DDP-ms)in combination with PBF(DDP,BLM,5- Fu)had been used in 14 cases with regional relapsed nasopharngeal carcinoma and 3 cases of untreated locally advanced nasopharngeal carcinoma got positive response.The result showed 2 patients with Cr,13 PR,1MR and 1 NC advanced cases with PR.The total suc- cessful rate(CR+PR)was 88 24%(15/17),In addition,the main toxicity and coplicaton had been discussed.

BACKGROUND:As the complexity of human anatomic structure,the abnormity of tissue shape and the difference among individuals,the structure of multifractal is adapted.OBJECTIVE:To investigate medical image segmentation based on multifractal.METHODS:Image segmentation was performed by algorithm based on capacity measurement and probability measure.The experimental images were segmented using traditional region growing,max capacity measurement,sum capacity measurement,and probability measure.Following adding noise,the images were identically segmented and compared.RESULTS AND CONCLUSION:In the two algorithms based on multifractal,the key of the algorithm based on capacity measurement is that appropriate measure μα is defined,and the key of the algorithm based on probability measure is that appropriate normalized probability Pi is defined.The different measures (probability) and thresholds bring greater effect.The method based on probability measure is sensitive to noises,but after filtration noise,segmentation effect is greater for the images whose pixels vary comparatively great and very complicated.The results show that it is feasible that appropriate measure (probability) and threshold is chosen based on medical image segmentation.Especially greater advantage exists for the distinction of texture and edge in the complicated image processing,which can reserve details while precisely dividing.It has very significant practical significance.At the same time,multifractal can also be characteristics of images,which provide powerful data for feature extraction.

There are two types of Chinese medicine, i.e., "Shihu" and "Tiepi shihu", using the stems of species of Dendrobium (Orchidaceae) as original materials. In order to understand species of Dendrobium using in Chinese medicine, taxonomic investigation and revision were performed. Our results indicated that about sixty species of sect. Dendrobium, sect. Formosae, and Sect. Stachyobium, are used as raw materials of "Shihu". Seven species of Dendrobium moniliforme complex and four species in Dendrobium officinale complex were recognized.

[ABSTRACT]AIM:Toobservetheeffectsofpuerarincombinedwithsaxagliptinonrenalfibrosisintype2dia-betic rats.METHODS:Fifty male Wistar rats were used, of which 8 rats were randomly chosen as normal control group , and the remaining rats were used to establish the type 2 diabetic model.The rats that met the criterion for the diabetic mo-del were randomly divided into model group , puerarin treatment group , saxagliptin treatment group , puerarin combined with saxagliptin treatment group and metformin combined with saxagliptin treatment group .The above-mentioned drugs were ad-ministered for 8 weeks.After that period, all rats were sacrificed.The kidney index (kidney weight/body weight),and blood glucose and HbA1c were examined in all the rats.The morphological changes were observed by HE and Masson stai-ning.The levels of TNF-αand macrophage migration inhibitory factor (MIF) in the serum were measured by ELISA .The mRNA expression of TNF-α, MIF and CD68 was examined by RT-PCR.RESULTS: Compared with normal group , the kidney index, blood glucose and HbA1c, the levels of TNF-αand MIF in the serum and the mRNA expression of TNF-α, MIF and CD68 were increased (P<0.05) in the kidney tissues of model group .Compared with model group , the kidney index, blood glucose and HbA1c, the levels of MIF and TNF-αin the serum and the mRNA expression of TNF-α, MIF and CD68 were decreased ( P<0.05) in puerarin combined with saxagliptin treatment group .CONCLUSION:Puerarin com-bined with saxagliptin reduces blood glucose , decreases MIF and TNF-α, and down-regulates the mRNA expression of TNF-α, MIF and CD68 in the kidney tissues of type 2 diabetic rats, which may contribute to the inhibition of renal fibrosis .

Objective:To quantify the tryptase and T cell immunoglobulin mucin domain-3(TIM-3)double positive mast cells in hu-man chronic periodontitis tissue using double immunofluorescence staining.Methods:25 healthy controls,28 chronic mild periodontitis and 30 chronic advanced periodontitis patients were included.The gingival specimens were stained with HE for histology,and with double immunofluorescence staining for the identification of tryptase and TIM-3 double positive mast cells in gingival tissue.Results:In chronic periodontitis tissue the degree of gingival inflammation was significantly increased,the densities(cells/mm2 )of tryptase and TIM-3 double positive mast cells were significantly increased(P<0.05),in addition,that in chronic advanced periodontitis group was significantly higher than in the chronic mild periodontitis group(P<0.05).Conclusion:Tryptase and TIM-3 double positive mast cells has the similar tendency as the severity of periodontitis inflammation in human periodontitis tissue.Tryptase and TIM-3 double positive mast cells may play an important role in human chronic periodontitis.

OBJECTIVE To find out the status about detection and drug resistance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) of urogenital tract infection in Shaoxing area of Zhejiang Province.METHODS The detections and drug sensitive tests of Uu and Mh adopting the reagent boxes produced by bioMerieux Company in France were made.RESULTS In 2678 samples of suspicious urogenital tract infection patients,980 samples cultured of mycoplasma were positive,and the positive rate was 36.6%.Among these cases,763 samples(28.5%) were Uu positive;116 samples(4.3%) were Mh positive.In the drug sensitive test,Uu and Mh were most sensitive to PRI,JOS,DOX and TET.To CFLX,OFL,ERY,CM and AM,they had the highest level of drug resistance.CONCLUSIONS The clinical therapy of mycoplasma infection ought to choose the appropriate antibiotics based on the results of the drug sensitive test of the laboratory.
